How to Deploy cert-manager and Automate SSL Certificates in Kubernetes

·2 views

cert-manager is a widely used Kubernetes add-on that automates TLS certificate issuance and renewal by integrating with ACME-based authorities like Let's Encrypt. The setup involves installing cert-manager via Helm on a multi-node Kubernetes cluster and configuring a Let's Encrypt ClusterIssuer to handle certificate requests. A sample application routed through Traefik can then be secured by annotating its Ingress resource to trigger automatic certificate provisioning. Once deployed, cert-manager monitors certificates and renews them automatically 30 days before expiry, with manual renewal also possible via the cmctl tool. Common issues such as DNS propagation delays and Let's Encrypt rate limits can be mitigated by waiting for DNS resolution or switching to the staging issuer during testing.

Most Germans Confused by New Automatic Tax Reporting for Platforms and Crypto

Germany's Platform Tax Transparency Act (PStTG) and crypto reporting law (KStTG) took effect in January 2026, requiring platforms like eBay, Airbnb, and Coinbase to automatically report user income to tax authorities. A representative survey of 1,010 Germans conducted by Norstat in January 2026 found that 52.9% feel unsure or totally overwhelmed about correctly declaring such income, while only 16.1% feel fully confident. Contrary to expectations, younger digital-native cohorts are not the most confused — the 'totally overwhelmed' share rises sharply with age, reaching 25% among those aged 60–64 compared to just 7.4% among 30–39-year-olds. A gender gap also exists, with 55.4% of women reporting low confidence versus 50.0% of men. The findings suggest that automatic reporting has not translated into taxpayer confidence, particularly among older Germans least likely to use these platforms.

Developer finds context, not design, is the real challenge in AI website generation

A developer building an AI website generator discovered that crafting prompts was not the hardest part — accurately capturing business context was. The AI struggled to differentiate between industries, often producing generic layouts unsuitable for specific businesses like plumbers or coffee shops. Shifting focus from HTML refinement to feeding the model detailed business information — industry, services, goals, and customers — dramatically improved output quality. However, once sites were generated, business owners still needed to frequently update details such as hours, phone numbers, and photos. This led the developer to conclude that the true product is not website creation but long-term site maintenance, an area where most website builders fall short.

Piano app data shows spring starters far outpace January learners in 6-month retention

An analysis of data from over 1.1 million learners on Skoove, an online piano platform, found that the month a person begins learning strongly predicts whether they continue six months later. The dataset, covering 2021 to 2024, shows that December and January sign-ups had the worst six-month retention, sitting 28% and 21% below the average respectively. By contrast, learners who started in spring months like May, April, and June retained at rates up to 23% above average. The gap between the resolution window and the spring window amounts to roughly 44 percentage points in six-month retention. Researchers suggest resolution-season starters may be motivated by calendar pressure rather than genuine interest, though the dataset does not directly capture reasons for quitting.
